Programming, machine learning, media management, gaming, browsing, 7zip compression. Only issues I've had have been the corsair memory being incompatible (not the current set), the front of the case restricting airflow (fix by opening the front under load). I bought the GPU off my friend who was selling it because it kept crashing in over-watch and nothing else, it works fine for me.
CPU is overclocked to 3.9GHz @1.35V and Hyper 212 does not let it get above 65C. Both memory kits are running at 3000MHz for a total of 48GB. This system works well on Ubuntu / Debian as well.
